Thank you sir. Very helpful!

Tysm sir I learned it very simply because of you

Thank you sir, it was very helpful.

Why you don't use screw gauge sir

After 1 hour I have my practical exam and i am watching this video now😭

May i know why do u use rheostat here??

Sir ek doubt hai ki hum jo wedges ke beech mein distance rakhte hai initially woh hum kuch bhi rakh sakte hai na ?

According to Indian ac frequency it would come under a 50 hz then sir as per your result it would 51.something so it is correct or incorrect

No use of rheostat here...

Where is the theory for this sir?

Can we start with with 50 , 100 weights also instead of 200

Sir formula is different in NCERT MANUAL.It is 1by 4l
